(3)閘刀開關技術參數與選擇
閘刀開關種類很多,有兩極的(額定電壓250V)和三極的(額定電壓380V),額定電流由10A至100A不等,其中60A及以下的才用來控制電動機。常用的閘刀開關型號有HK1、HK2係列。表1-1列出了HK2係列部分技術數據。
正常情況下,閘刀開關一般能接通和分斷其額定電流,因此,對於普通負載可根據負載的額定電流來選擇閘刀開關的額定電流。對於用閘刀開關控制電機時,考慮其起動電流可達(4-7)倍的額定電流,選擇閘刀開關的額定電流,宜選電動機額定電流的3倍左右。
(4)使用閘刀開關時應注意:
·將它垂直的安裝在控制屏或開關扳上,不可隨意擱置;
·進線座應在上方,接線時不能把它與出線座搞反,否則在更換熔絲時將會發生觸電事故;
·更換熔絲先拉開閘刀,並換上與原用熔絲規格相同的新熔絲,同時還要防止新熔絲受到機械損傷;
·若膠蓋和瓷底座損壞或膠蓋失落,閘刀開關就不可再使用,以防止事故。
